DOOR.

Specification of Letters Patent. Application filed March 9, 1912.

Patented Feb. 3, 1914. Serial No. 682.825.

do it known that'l. (HARLES Moscn, a subjer-t. of the Emp ror of(tel-many. residing at lortland in the eounty of hlultnomah and State ofOregon. have invented certain new and useful ltl|])."t)\tt)h3ltl inDoors. of \\'l)l('il the following is a --peeiti('atiou.

This invention relates: doors. and the primary tion is to provide adoor-which may be utilized either as a solid panel or glazed door inMold weather or may be utilized as a screen door in hot weather, withoutbeing removed from its hinges.

secondary objeet of the invention to provide a slidahle panel or doormember and simple and etticient means for operating the said panel andholding it in its, raised position.

A further objeet of the invention is generally to provide a door whichwill be neat. in appearance and which will be strong and durable andinexpensive to produee.

The invention is fully illustrated in the accompanying drawings and willhe'hereinafter deseribed in detail. the novel features of the same being-.ul. sequently pointed out in the appended claim. a 1

tron, with intermediate portions broken away whereby to more elearlyshow the detail eonst-rurtion and arrangement of the essential parts ofthe invention; Fig. 5 is a seetional view taken on the line 5-5 of Fig.t; Fig. t3 l. a horizontal seetion taken on the line tlti of Fig. t;Fig. 7 is a detail perspective view showing a portion of the edge of theslidable panel and the means for attat'hing the same to the operatingeable: Fig. 8 is a detail view showing one of the pulls-or handles onthe sliding panel.

in carrying out myinvention. l unploy 2 frame eonsisting of the stiles land the uppe and lower rails 2 and 3 and intermediate bar 4 connectingthe stiles. The inter mediate bar-t is reeessed at its ends as shown bydotted lines in Figs. '1 and l. and holding or retaining stripe 5' aresecured to the stiles and extend aeross the rails and the. saidintermediate bar so as to impart a some;

to improvements in l t i 'in the lower edge of the rail and the side asthe same is wound upon the shaft.

in the frame. and the lower edge of the what ornamental appearance tothe door and also to permit access to the operating parts as will hepresently set forth. These several retaining strips are secured to thedoor trame by Screws (3, preferably, in order that; the removal andreplacing of the bars will not cause undue injury to the material ofwhich the frame is made. The lower portion of the frame, that is to say,the part between the lower rail 3 and intermediate bar 4 may be finishedin any desired manner to present a solid panel 7 while the portionbetween the intermediate bar and the upper rail isle ft open to becovered by a sliding panel hereinafter more particularly described.

The inner or facing edges of the stiles are provided longitudinalgrooves S in which the operating cord or ea ble 9 plays, the said word75 etmstituting an endless belt passing arsamd pulleys 10 mounted inreeesses l1 near the lower ends of the stiles and similar pulleys 12secured rigidly on a shaft or winding rod 13 which extends through theupper rail and is journaled in bearing plates 14 secured in recesses 15nea' the upper ends of the stiles. The upper rail is provided with alongitudinal recess or cavity or chamher to to aeetmnnodate a shaft orwinding rod 13 and a sereen 17, preferably of wire nettingis secured tothe said shaft or winding rod and adapted to wind upon or unwindtherefrom in the operation of the invention. A longitudinal slot 15 isformed 0 walls ol,tl1e said sl. diverge upwardly, as shown at 1!) inFigs. 2. and 3, so as to accommodate the inelined position assumed bythe downwardly extemling portion of th'e sereen I he lower edge of thesaid screen is secured to a sliding panel or frame 20 which is mountedbetween the stiles 1 and adapted to move downwardly through theintermediate bar 4 and into a ehamber 21 formed behind the lower panel7, as will he readily understood upon reference to Figs. 2 and 3. Thispanel or frame 20 may be equipped with an orna mentalbolid opaque plate.but is preferably glazed. a pane of glass being indieated in thedrawings. The pane f2 is seeured within the frame by means of moldingstrips 23 fitting against the pane and upon rabbets formed sereen 17 isseeured in the upper edge of the said frame 20 by means of a moldingstrip 24 in a similar manner, as clearly shown. The upper retainingstrips 5 extend over the chamber 16 in the rail so as to protect thesame against the entrance of dirt and provide removable covers for thesaid chamber so that access to the parts may be readily had whennecessary.

Molding strips 25 are secured to the lower edge of the rail and spacedapart so as to furnish a groove or recess to receive the upper edge ofthe slidable panel when the same is raised and the lower edge of therail constitutes a. stop to limit said upward movement, allof which willbe readily understood upon reference to Fig. 2. Similar molding strips26 are secured upon the upper edge of the intermediate cross bar 4 toform guides for the sliding panel as well as to impart a neat andornamental finish to the door and additional similar strips 27 aresecured to the inner edges of the stiles so as to constitute guides forthe panel during its movement. Pivoted upon the inner face of theintermediate bar 4, at or near the upper edge of the same, is a. latch28 which, when the sliding panel is raised, is adapted to swing into theposition shown in Fig. 2

whereby the inner end of the latch will pr0- ject under tlre panel andconsequently support the same in its raised position. When it desired tolower the panel the free end of the latch is swung downward so that thelatch will. be disengaged from the panel, as will. be readily understoodon reference to Fig. 3, and to prevent excessive wear upon the upper endof the panel when the same is in its lowered position, I secure theretoa metal strip 29 against which the end of the latch will hear so thatthe pressure then exerted by the latch will not indent nor mar theppnel. The panel is connected to the operating cable 9 by a screw 30which passes through the cord 9 so that the move- -ment of the cord willnecessarily be imparted to the panel, and to prevent mutilation of thecord or belt by the screw a reintorcing sleeve or ring 3i is fittedaround the same at the head of the screw. In the side members of thepanel 20 and. in the inner faces of said side members, I provide handlesor pulls 32 which will furnish a (fOllVQlllUllli means-"of grasping thepanel when it desired to raise or lower the same. When the panel is inits lowered position the upper handles or pulls 32 will lie di-.

rectly behind the recessed ends of the intermediatcbar l so that if theintermediate retaining strip 5 be removed the handles may be reached andsutliciont force applied thereto to move the panel upwardly so that itsedge will project above the intermediate bar. The panel may then bereadily grasped so that it may be quickly raised to the limitof itsupward nu'wement'.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the use and advantages of myimproved door will be readily understood and appreciated. ln coldweather the panel. will be in its uppen most position, indicated in Fig.2. When the weather becomes hot or, for any other reason, outside air isdesired in the room, the latch 28 is depressed and the panel thenlowered into the chamber 21, its impact against the bottom of saidchamber being cushioned by rubber or other elastic lnifl'ers 33 therein,so that damage to any part of the door through dropping or too rapidlowering of the panel will'be avoided. To further guard against damagefrom this source I may provide triangular metallic plates 34 atintervals along the meeting edges of the panel and the lower portion ofthe stileso that'the contact between the overlapping points of saidplates will check the descent of the panel. The upper por tion of thestile will be beveled to avoid the wearing away of the same by theplates on the panel. As the panel is lowered it will, of course, pull.downwardly upon the screen 17 so as to unwind the same and draw itacross thespace being vacated by the panel so that when the panelreaches its, lowermost position the upper portion of the door will bescreened to prevent the entrance of flies or other insects but permitthorough ventilation. The belt or cable 9 will follow the movement ofthe panel and by its engagement with the pulleys will tend to retard thedescent of the anel and also will cause the screen to unw nd evenly sothat .wear upon the walls of the slot 18 will be minimized. In raisingthe panel, the screen would tend to buckle between the upper edge of thepanel ind the upper rail 2, but this buckling is av iided by theprovision of the cable or belt 9 which will positively actuate the shaftor winding rod 13 and thereby cause the screen to wind evenly andsmoothly thereon and at a speed determined by the movement of the panel.

it will be readily noted that my improved door is not bulky and that allthe operative parts are inclosed in the frame of the door so as to beprotected against injury, and as there is no'con'iplicated mechanism connected with the door the operation will. be

easy and frequent repairs will be unnecessary.

It will be understood, of course, that while l have shown and describedthe invention .valllillllll taining strips attached to the stiles andextending below the lower edge of the upper rail I ing chamber,

to fo'rln-ascreen receiving chamber, outer and inner panels supportedupon the lower rail and defining asash receiving space, a slidable panelvertically movable in said space, a winding shaft disposed in the screenreceiva'screen attached at one end to said winding shaft and at theother to the upper edge of the sliding panel, oppositely disposedpulleys mounted. upon the windin shaft, oppositely disposedpulleys mountin recesses in the inner faces of the stiles and below said panels, anendless flexible connection passlng over.each pair of upper andlowerpulleys and through the longitudinal groove of the stile, and aconnection between one flight of each endless connection and theslidable panel, the-pulleys being greater in diameter than the width ofthe groove the flexible connection pass whereby to frictionallyretardthe movement of the flexible connection.

In testimony whereof Iafli'x my signature in presenceof two witnesses.CHARLES MOSOH. 11. SJ
